Sandbaggy Concrete Slab Bolster Upper (also known as a beam bolster) provides great strength and durability with its 6 gauge steel and continuous design. Installation is effortless, simply placing it on the ground and positioning the rebar. Its continuous design ensures even support and spacing of the rebar.
Our Plain Slab Bolster Upper is great for a variety of applications, such as elevated decking, footings, slabs on metal decks, bridges and patios/sidewalks. It streamlines the rebar installation process, yields better concrete consistency and extends the longevity of concrete structures.
Sandbaggy carries a variety of concrete forming supplies.
Slab bolster uppers are type of rebar rod chair used to space layers of steel or support steel on soft material surfaces. They feature two runner wires connected by evenly-spaced legs and topped with a supporting wire, available in various heights and lengths for project-specific needs.
Slab bolsters are regularly employed in concrete construction for applications such as:
Slab bolsters secure rebar to the correct positions, promoting the reliability and endurance of the concrete structure.
A typical spacing for slab bolster uppers is 5 inches on center, please note this may vary depending on the application and advice from an engineer or architect.
Slab bolster uppers provide a structural foundation to hold one layer of steel above another, while slab bolster lowers are meant to support the bottom steel rebar in a concrete slab.
A Concrete beam bolster (also known as a rebar bolster) is used to support lower beam steel from the slab form. Concrete bolsters are available in a variety of sizes to meet the specific needs of each project.
